find_all关键字根据官方介绍的作用是查找所有出现GUI元素,并且返回list,下面通过举例说明
def find_all(predicate):
"""
Lets you find all occurrences of the given GUI element predicate. For
instance, the following statement returns a list of all buttons with label
"Open"::
find_all(Button("Open"))
Other examples are::
find_all(Window())
find_all(TextField("Address line 1"))
The function returns a list of elements of the same type as the passed-in
parameter. For instance, ``find_all(Button(...))`` yields a list whose
elements are of type :py:class:`Button`.
In a typical usage scenario, you want to pick out one of the occurrences
returned by :py:func:`find_all`. In such cases, :py:func:`list.sort` can
be very useful. For example, to find the leftmost "Open" button, you can
write::
buttons = find_all(Button("Open"))
leftmost_button = sorted(buttons, key=lambda button: button.x)[0]

2、方法二:通过 find_all(S("table > tbody"))获取表格数据
代码如下
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | from helium import *import timedef gaokao(): start_chrome("https://gkcx.eol.cn/school/search") time.sleep(2) wait_until(Text("学校名称").exists) list = [] for i in find_all(S("table > tbody")): highlight(i) print(i.web_element.text) list.append(i.web_element.text) time.sleep(1) return list kill_browser()gaokao() |
